The problem is that white has no way to prevent the Black king's intrusion.
Averbakh's plan and tactics are plain brilliant from beginning to end. Note the
nice tactics on 48...Bg1+! and 51...f5! and of course 57...g4!!
Just for your information, I played out this plan against Shredder 7.04 on my
Athlon 2400XP+, letting it think for at least a minute for each move (reaching
22 plies depth on average) and had no problem winning. If you think you can
improve on white's play we can duke it out in this thread (which will stay
discretely at the bottom of CCC and shouldn't bother anyone) and you can see for
yourself, as well as any other doubting Thomases. Here's the score:
[Event "?"]
[Site "?"]
[Date "????.??.??"]
[Round "?"]
[White "Shredder 7.04"]
[Black "Albert Silver"]
[Result "*"]
[SetUp "1"]
[FEN "8/2p5/5p1p/5Bp1/3k4/2p2PbP/4K1P1/8 b - - 0 1"]
[PlyCount "43"]
1... Ke5 2. Bh7 Kf4 3. Be4 h5 4. Bd3 h4 5. Be4 c5 6. Kd3 Be1 7. Ke2 Bd2 8. Bd3
Kg3 9. Kf1 Be3 10. Bc2 Bf2 11. Bd3 f5 12. Ke2 f4 13. Kf1 Be3 14. Bc2 g4 15.
hxg4 h3 16. gxh3 Kxf3 17. Bd1+ Kg3 18. h4 Bd4 19. h5 Bf6 20. h6 f3 21. Bb3 Kxg4
22. Ke1 Bd4 *
You can challenge me to the position after 1...Ke5 if you like,
[D]8/2p5/5p1p/4kBp1/8/2p2PbP/4K1P1/8 w - - 0 2
and feel free to use all the engines you like. This is only to say I think the
plan is clear and there is nothing to do to stop it.
